I bought this tire at the time of a new trainer purchase. I have about a month's worth of solid riding on it and have had three flats. The tread on the tire is not perfectly inline with the casing, so it vibrates in spots as the tire rotates despite the bead being seated fully on the rim. After inspection, the casing has separated from the tread and is wearing on the tubes. Maybe I have a defective tire, but I would fully check the tire prior to purchase if possible.
